How to reduce swelling after knee replacement at home?

Some swelling after knee replacement is normal and can continue for several weeks or even months while the tissues heal. The aim at home is to control swelling without reducing necessary movement.

What can help reduce swelling

• Use a cold pack for short periods as advised by your surgical team.
• Elevate the leg so the knee and ankle are supported comfortably.
• Avoid sitting or standing in one position for long periods.
• Continue the physiotherapy exercises prescribed after surgery.
• Walk regularly in short sessions rather than doing one long walk.
• Take pain and anti-inflammatory medicines only as prescribed.
• Follow instructions about compression stockings if they have been recommended.

Mild swelling or warmth can persist during recovery, especially after activity. ASIC Clinic notes that improvement continues gradually over several months after knee replacement.

When swelling may be a warning sign

Contact the surgical team if swelling suddenly increases or is associated with:

• New calf pain
• Increasing redness
• Wound discharge
• Fever
• Chest pain
• Shortness of breath

These symptoms can sometimes indicate infection or a blood clot and need prompt medical assessment.

Dr. Atul Mishra and the physiotherapy team adjust activity and rehabilitation according to each patient’s progress. Swelling should generally improve over time rather than become progressively worse.
